APPARATUS FOR '.PREVENTING DISTURBANCES 0F TH STATE vr0F HEALTH DUEVTO SEESAW AND ROTARY MOTIONS.

AApplication nled Hay 9, 1927, Serial No. 189,998Qand in Austria July 29, 1926.

When the static organ is exposed to see saw and rotary motion, disturbances of the state of health are caused which manifest themselves in the `first place by giddiness, vomiting, salivation, headache and the like. These disturbances are most felt in sea and air travels. p

The subject matter of the present invention is an apparatus which permits to prevent these disturbances. The `apparatus is more particularly distinguished by great simplicity and ready portability, so that any person can carry it with him or her at all times during a travel on the sea or in the air and may use it at will without his or her other occupation beingl interfered with.

According to the invention the static or-` gan is exposed during the see saw or rotary motion to a weak electric current entering near the static organthat isto sa the an'ode of an electric circuit is applie near Vthe static organ. The cathode of this circuit is preferably applied to the forehead or four volts is sufficient.

to the neck or to the breast, that is to say preferably in the line of symmetry of the body. As a source of electricity, for instance a dry battery of a voltage of about The intensity of current thus set up is about 2 to 3 milliamperes,fand therefore the battery may sufice for days. i

It has been found that the disturbancesv `due to see4 saw or rotary motions are suppressed completely or to the major part when an anode is applied to each of the two mastoid processes. It f is essential that through both static organs a current of practically the same intensity should pass as otherwise disturbances of equilibrium may readily occur.

Fig. 1 of the drawing shows the apparatus in position on a patients head. Fig. 2 is a plan view showing battery connections.

The apparatus is preferably constructed of a frame 1 resembling a head telephone, the two anodes 2, 3, being mounted in such a manner lthat on putting on the frame in the usual manner, the two anodes come into contact with thel mastoid processes undera slight pressure, see Fig. 1. Preferably on the frame 1 a strap 4 is arranged whichcarvalready dried.

ries the cathode 5 in such a manner that this cathode bears with slight pressure against the forehead or the neck. The connection with the source of current is preferablyV such that any mistake as regards the poles is excluded. For Athis purpose advantageously a plugcontact is used which does not permit of any mistake as regards the poles.

The cathode 5 ma be placed on anyother part of the body, or instance on the arm and therefore the `bearing point of the cathode may' be readily changed whenever the continued application to the forehead or the neck causes any inconvenience.

The current intensity of 2to 3 milliamperes being so small that' it can be endured without any obnoxious bye eHects for hours and days, as has been found by special experiments, the use of any control device may be dispensed with which in turn results in that the weight of the apparatus may be very small, any person may carr it with him or her at all times and that it may be mounted ready for use or dismounted within a few seconds.

In order to keep the electrodes slightly moist for a longer period of time, the sponge attached to the electrode in the usual Way is preferably made slightly greater so that it also covers the back of the electrode. If the part of the sponge pressed a ainst the body by the electrode with a slig t pressure becomes dry it is only necessary to squeeze the sponge at one or` more'points. Thereby the liquid contained in the spon e at these points is forced into the What I claim is: v
